RatRig V-Core 3 Bed Arms heat-set insert mod

You will need

8x M3 Brass heatstake inserts - short M3x5x4
6x M3x8 Countersink screws (for the magnets)
2x M3x10 Cap head screws (for the bed cable relief)

This mod will give you bed arms a nice and clean look and you don't have to worry about dropped nuts anymore. You won't see where the heat insets have to be put under the magnet because of the thin bridge which is used but if you use the magnet to find the spaces where to push it will work fine.
